2. double click the selected filter
   - options available:
     - from signal
     - connect to script
     - receiver method
       - you can also click on "Pick" next to receiver method so that you can choose a different method that already exists

3. click connect and the boilerplate code will appear in the script you had selected in the signal creation pane above in (2)

   - if you look at the node pane on the right and scroll to the signal, you'll see a green indicator showing that you have connected that signal (to something)
